Which exhaust setup are you running now? Magnaflow or Porter

still the mufflex 3.5" single with the single custom porter muffler. the magnaflow is under the workbench lol

that's one thing that's wild, it's definitely a very distinct sound, compared to the borla/8802 cam and osies procharged 385 with the same mufflex/magnaflow. when I had the mufflex magnaflow we started my car and his car at the same time and mine definitely sounds way different because of the cam

Looks better from that angle. The earlier photo appeared to show the TB under the wiper mount.

Still need to keep the air path away from the wiper mount, so it limits the distortion, and produces even air flow into the throttle bores.

Are you going to keep the Ram Air hood? Air's going to be kinda warm before it gets to the TB. Maybe opt for a cowl hood, for direct, cool air flow to the throttle bores?

i didnt see any issues with iat on the low rise vic efi intake at the rental. the engine is in no way going to max out this throttle body, this flows 1250cfm peak with no spacer. the engine doesnt even flow that much. in the data from the rental with the iat right next to the tb, yea at idle it was warm, but the second i cracked the throttle on the footbrake it was only about 10-15 above ambient, and once i went wot within the 60ft (approximately 1.5 seconds into the run) the iat was only a few degrees above ambient. the ram air hood unrestricted the way it is, once i am moving down track with any mph there is cool air flowing across the whole top of the engine. iat adders are turned off in my tune since the iat was relocated before with the elbow.

i really do not want to change the hood to a cowl, i do not like the look, and i thought you wanted me to not mess with the body lol. about the ONLY cowl hood i would consider is the low rise sunoco style cowl (think ram air with no ram air nostrils, wide cowl)

i thought about making a super sucker style tray like some of the ls1 single plane guys did to use the ss style hood opening as a functional opening. right now just gotta get it sorted first before we start chasing hundreths of a second.
